What is Space debris:

  • The first-ever satellite was launched by the then Soviet Union in 1957. Since then thousands of satellites have been launched. Some of them are no longer functioning. They sometimes collide with each other and smash into thousands of pieces. All these pieces and the defunct satellites are called “space debris” or “space junk”.

The need to tackle space debris:

  • Space debris is a risk to the functioning satellites and astronauts. In November 2021, a chunk of a Chinese satellite almost hit International Space Station (ISS). This makes us realize the importance of tackling space junk.
  • Earth’s gravitational pull attracts space debris back into the earth. Some objects burn up when they enter Earth’s atmosphere, but some larger objects do not burn. But fortunately, most of them fall into oceans since Earth is mostly covered by water.
  • Due to the possible collisions with satellites, Low Earth Orbit (LEO), where most of the artificial satellites are placed may become unusable.

Space junk removal:

  • Several space agencies such as NASA and ISRO are working on developing technologies to remove space debris.
  • A Japanese company launched “End-of-Life Services by Astroscale-demonstration” (ELSA-d) in March 2021 to clear up space junk. The demo was performed in August 2021.

How can we avoid future space junk:

  • Some satellites are made to burn up in the atmosphere and some satellites are sent even farther away from Earth.
  • ISRO (Indian Space Research Organisation) is developing “Self-eating rockets” and “vanishing satellites” to prevent future space junk.

Defunct satellites in space are a big risk to the functioning satellites. Several space agencies such as NASA and ISRO are working on developing technologies to remove space debris. They are also working on new technologies to avoid future space junk.

    Space debris is a serious threat to mother earth and ultimately to mankind. There is no denial from the fact that the 5g we are using is possible due to the presence of satellites. The debris in space will collide with one another and a domino effect will be seen which will upheave their arrangement. The loss will be huge because we are dependent on the satellite to gain insights about weather forecasting, surveillance of other countries for security purposes and this digitalized era will no longer remain the same if space apocalypse occurs.
